Twin Oaks
Also known as: Winsor Hall
Why it's listed
Twin Oaks is a two-story, wood-frame Greek Revival plantation house on a knoll in Greenville, Georgia, surrounded by about 49 acres that once formed part of a 300-acre plantation. Begun about 1855 for planter and early cotton mill owner J.M.C. Robertson, it has a six-column Doric portico, a low hipped roof, a stuccoed brick basement and a central-hall plan of four rooms over four. Elbert Wimbish, a skilled enslaved builder borrowed from Dr. Hezekiah Wimbish, constructed it. The house has kept its original appearance, and a detached kitchen survives from the nineteenth century. Oak trees and the hilltop siting reflect the landscape ideas of the period. The site also held the log home of early settler Jordon Rees. A 1979 archaeological investigation located outbuildings and the original front steps and suggested that more could be learned about plantation life, including a possible slave burial ground nearby.
Significance in brief: The nomination argues the house is a well-preserved example of antebellum Greek Revival architecture, built by a slave craftsman, Elbert Wimbish. The grounds reflect Greek Revival landscape design, and the site is tied to the early local history of planter and cotton mill partner J.M.C. Robertson. A 1979 archaeological survey also showed strong potential for further historic archaeology.
